If you don’t have one of your own, try making one up. The easiest thing to do is to substitute your own words to a tune or song you already like. If Barney isn’t your style, you can try something more contemporary. My kids like this song from Yo Gabba Gabba. It’s easy to change “Let’s dress up!” into “Let’s clean up!” Ad lib your own lyrics to the clean up situation “everybody in the house clean up, put all your toys away. If you want to go outside, you better get them away.”
